Cookie Policy
Last updated: 12 February 2026
1. What Are Cookies?
Cookies are small text files stored on your device by your web browser when you visit a website. They serve various purposes such as remembering your preferences, maintaining your session, and providing security features. Some technologies like "localStorage" and "sessionStorage" serve a similar function and are also covered by this policy.
2. Cookies We Use
We use one cookie, and it is strictly necessary for security. We do not use any tracking, analytics, or advertising cookies.
| Name | Type | Duration | Purpose |
|---|---|---|---|
oauth_state |
Strictly necessary | 10 minutes | CSRF protection during Google sign-in. Prevents cross-site request forgery attacks. This cookie is httpOnly (inaccessible to JavaScript) and is deleted immediately after authentication completes. |
Because this is a strictly necessary cookie (required for security), no consent is needed under GDPR/ePrivacy regulations. There is no cookie consent banner because we have no optional cookies to consent to.
3. Browser Storage (localStorage and sessionStorage)
In addition to cookies, we use your browser's built-in storage to maintain your session and preferences. Unlike cookies, these are not sent to our servers with every request.
| Storage Key | Type | Purpose |
|---|---|---|
authToken |
localStorage | Keeps you signed in across page loads. Cleared on logout. |
refreshToken |
localStorage | Allows automatic session renewal without re-entering your password. |
additionalLanguages |
localStorage | Remembers your preferred translation languages across sessions. |
selectedPersonaId |
localStorage | Remembers your last-used AI writing persona. |
primaryLanguage |
sessionStorage | Current import language selection. Cleared when you close the tab. |
batchLanguages |
sessionStorage | Languages selected for the current batch. Cleared when you close the tab. |
All browser storage data stays on your device and is used only to improve your experience within the application. None of this data is sent to third parties.
4. What We Do Not Use
- No analytics cookies (Google Analytics, Mixpanel, etc.)
- No advertising or retargeting cookies
- No social media tracking pixels
- No fingerprinting or cross-site tracking technologies
- No third-party cookies of any kind
5. Managing Cookies and Storage
You can control cookies through your browser settings. Most browsers allow you to block or delete cookies. However, blocking the oauth_state cookie will prevent Google sign-in from working (email/password login will still work).
To clear localStorage and sessionStorage data, use your browser's "Clear site data" or "Clear browsing data" feature, or open Developer Tools (F12) and navigate to the Application/Storage tab.
6. Changes to This Policy
If we add any non-essential cookies in the future (e.g. analytics), we will update this policy and implement a consent mechanism before deploying them. We will notify you of material changes at least 30 days in advance.
